We will either be extinguished by a technological accident of some kind (biological warfare experiment gone awry being perhaps the most likely cause) or be altered by technology to the point of being unrecognizable as human. So? Yes, humans a few hundred years from now will look quite different from humans today, but I'm quite content with that, as they'll still be our descendants (and some of them may actually be some of us -- my cryonics arrangements are in place, how about you?). Nope. I don't share your faith in the future's hospitality to corpsicles. Maybe they'll keep you frozen in a lab for historians to puzzle over, maybe they'll thaw you and put you in a terrarium in somebody's basement. Whatever supplants us will almost certainly be quite different from us, may not be our "descendants" in any biologically meaningful sense, and may not have any interest in wetware at all. This is NOT equivalent to humanity being wiped out. Not even a little. To argue for the equivalence of these two outcomes is absurd. I'm not saying those outcomes are equivalent, just that it is more than a little naive to plan today for our descendants to be stepping down out of airlocks onto alien planets circling distant stars. And it depends what you mean by "humanity." Whatever replaces us might be less human than a chimpanzee. And eventually less human than a turnip. I'm not even sure how much difference it will make if such beings result from our efforts or someone else's. -- Roy L |

![]() I dont think whatever the human race morphs into matters as long as we or what ever we morph into moves and spreads out into the universe. I dont see the US attacking any country militarlly because they beat us in space. We might attack a country economically if they beat us in space, but its more likely NASA would get a huge buget to work with. Ray wrote in message ...

We will either be extinguished by a technological accident of some kind (biological warfare experiment gone awry being perhaps the most likely cause) or be altered by technology to the point of being unrecognizable as human. Natural selection would take perhaps 10Ky to produce a noticeable difference in our species, under strong selection pressure. Given what technology has wrought in the last 100y (and genetics in the last 50), is it really likely that we will still be going about our Sims-like lives in the year 12005? How about the year 102005? It's on the order of 100Ky since our species assumed its present character. It's got to be about something more important that just some dam robot probe doing science on another planet! That is true, and it is. It's about Life, which occupies the available niches. It's also about controlling the high ground, which confers military superiority. This much I can tell you: if the growing Chinese presence in space come to be seen as potentially outstripping the US presence, the USA will either increase its space spending to maintain its superiority, or attack China economically or militarily in order to slow or stop its progress into space. -- Roy L |

This last point is probably more important to us in the near future. I wish that this were the reason given to the American people as the reason for human space exploration. It's got to be about something more important that just some dam robot probe doing science on another planet! Space exploration is not something that can put put off until we "really need to put people in space" or until we have no choice but to reach out into space because it might be too late at that time in the future. Real space exploration into the solar system, out of the solar system into the galaxy and beyond might take centuries or eons to master for the human race. Thats why we have to start with small steps now to the moon, mars and beyond or I believe the human race risks extincting when it does not have to become extinct. Now its true that their might not be immediate danger of extinction now and more pressing needs on earth and thats why we need to start out with small steps into space now. What do you all think? Nicely put. A bad scenario is that of some of the peak oil crowd. Increasing fuel costs lead to the lower incomes in some resepcts the reversal of society. This would make a space program harder, and more people will say "our incomes are falling, we can't afford space exploration". In fact, there's a blog at peakoil who says that NASA should be redirected from Space Exploration and focused on energy research. A good answer from NASA might be along the lines of: "Please go and read GK O'Neill's High Frontier". |

Why would you bring NASA into it if the energy research you want doesn't involve space development (most likely, SPS)? FWIW, I tend to agree. "Exploration" is a luxury, and one that can be carried out just fine by private (for-profit or not) organizations. What we really need from NASA is infrastructure development, and particularly given our current and coming energy crisis, more options for energy production. (Yes, free markets might eventually develop those too, but it might be too little too late; one valid purpose for government is to invest in things that are too risky, or have a horizon too far away, to interest private investors.) ,------------------------------------------------------------------. | Joseph J.

Here's the discussion: http://groups.google.co.uk/group/sci...0c193e 60bf26 It was pretty clear - focus NASA on short term energy innovation. |

Best way I've ever heard it put was by John Michael Struzinsky writing for an interview of Commander John Sheridan (played by Bruce Boxlineger) in one of Babylon 5's episodes. It should be REQUIRED reading for all politicians at ANY level, as to why we HAVE to go into Space. If the media or officials could put it on these terms, The Public would at least understand better why establishing the groundwork for space travel is ABSOLUTELY MANDATORY if we are to be anything more than just a interesting but minor experiment in the history of the universe. Next time someone says that we should spend "all that money HERE on Earth", remind them that it IS spent here on Earth, and ask them how bad they think Hurricane Katrina would have been if we hadn't had the advance warning weather satellites and the 40 years of experience tracking hurricanes they've given us. Then remind them that NASA's budget breaks down to about the cost for a pizza or two every year for each family. BTW, shouldn't this thread be in sci.space.policy? |

The problem with that idea is the amount of time that is going to pass before the Sun dies...which is in about five billion years. It's thought that Homo Sapiens emerged as a separate species around 130,000-150,000 years ago. So, it's going to be around 30,000 to 40,000 times the entire history of our species before that happens. So we don't have to migrate to other heavenly bodies in the in the next fifty years...or even fifty thousand years, for that matter. As far as it goes, Pat, you are right. But, theres one fly in that ointment. Granted that the Earth and the Sun will still be here five billion years from now ( Barring any changes coming from the Vorlons... g ), but the Sun has it's fuel supply, and the Earth doesn't need one. Only we life forms do, and only we technological civilisation life forms need resources that are rather non infinite right now, only a mere century or so, since their consumption began. It may well be, that if we don't get a civilisation planted off of this rock, and have it be at least self sufficient, before we run out of go juice down here, that the ability of any human civilisation to move off planet might well not exist in a hundred years, even if those around then really want to do such. The loss of margin between oil supply and demand of the last couple of decades ought to give a clue in that direction. Andre -- " I'm a man... But, I can change... If I have to... I guess.
